Roller bearing with cushioned track

摘要

A pair of parts rotatable relative to each other about an axis are relatively supported by a roller bearing having a radially directed and angularly extending annular track unitarily formed on one of the parts and centered on the axis. The other of the parts is formed with a groove open toward the track and holding a track ring centered on the axis and formed with an annular track radially confronting the track of the one part and a cushion ring supporting the track ring in the groove on the other of the parts. An annular array of roller elements is provided between and engaging both of the tracks.
